Repligen Launches OPUS(R) Ready-to-Use Chromatography Columns With Largest Capacity Available On The Market

WALTHAM, Mass., March 26, 2014 (GLOBE NEWSWIRE) -- Repligen Corporation (Nasdaq:RGEN), a technology leader in pre-packed columns for the cost-effective purification of biologic drugs, today announced the commercial launch of its OPUS ® 45 cm diameter columns ("OPUS 45") with the largest capacity currently available on the market. OPUS columns, which now range from 1.2 cm to 45 cm in diameter, are delivered packed with chromatography media used to purify monoclonal antibodies and other biologic drugs. OPUS technology increases facility flexibility, improves the speed of process development and reduces the cost of biopharmaceutical manufacturing by decreasing the set-up, cleaning and validation times associated with traditional purification technologies. OPUS 45 was designed to process large single-use bioreactor harvests and will be formally launched at Biopharmaceutical Development & Production Week being held March 24-27 at the Hilton Bayfront Hotel in San Diego.

In November 2013, Repligen completed a 9,000 square foot expansion of its manufacturing facilities at its Waltham headquarters which included a dedicated production suite built to ISO 7 clean room specifications. As a result, the Company more than doubled its manufacturing capacity for its OPUS line of chromatography columns and established an appropriately controlled environment to satisfy the Good Manufacturing Practices (GMP) standards of the Company's biopharmaceutical customers.

OPUS chromatography columns are available and can be ordered through Repligen's bioprocessing product website: http://www.repligen.com/opus.
